One thing I'd suggest for an update would be overhauling the general animations to be more realistic and just generally better looking- for example, the run. Animals don't lift all four legs at once when running.
Maybe use some animations similar to AquaChocobo's for the walk, sit, lay, etc.- of course, probably not the buttswing, headbang, and etc. replacers, though roar could use Aqua's anim or something similar.
I dunno, I think it'd be nice to have something like that- or even a mod that keeps buttswing, headbang, and etc. as-is but fixes the walk, run, and etc.
